If anyone is on the fence about the new 2016 bundle, the resellers are out in force on Steamtrades buying up Rust copies for 1 CSGO key each. That's a pretty good deal considering the BTA price, so easy way to get something back for that one game if you own it or don't want it. You can easily sell off the key for $2, trade it for another game, or get a bit more in Steam wallet. Makes BTA less than a buck at the end of the day if you dont mind an extra step or two.
What makes Rust so popular with the resellers?
